TOP, The Output Processor®

Software for Visualizing Monitoring Data and Simulation Results

About TOP
TOP reads data from a variety of sources and transforms it into high quality graphics for inclusion in reports and documents.
TOP was developed by Electrotek Concepts® to visualize data from a variety of simulation and measurement programs.

TOP utilizes Microsoft's Multiple Document Interface (MDI) to allow you to
simultaneously view several different plots in multiple windows. You can move, size,
and arrange the windows on the screen as desired, and any window can be printed at a
command or keystroke. Because of the functionality offered by Microsoft Windows, TOP does not need to be updated every time a new printer or display
device is installed.

The data displayed in any window can also be exported to a file or pasted to the
Windows clipboard in a variety of graphical, numerical, or text formats. Supported
export formats include

PQDIF (.PQD)

COMTRADE (.CFG)

Windows Metafile (.WMF)

Portable Network Graphics (.PNG)

Comma Separated Value (.CSV)

ASCII Tabbed Text (.TXT)

Using TOP
TOP manipulates the data to be displayed using a mechanism called the stack
(illustrated below). First, you select a file that contains the data to be visualized. TOP then generates a dialog box displaying all of the quantities (objects) available in the current
file.

You then select the items of interest, which TOP loads into memory. This process is
similar to selecting a file folder from a file cabinet, selecting specific papers in the
file that are of interest, and piling them in a stack on your desk.

You can reactivate the dialog box at any time and load more data objects onto this
stack. You can also select another file at any time and load data from that file onto
the stack. The result is a stack of data objects of potentially different types and origin
that are now available for visualization. You can now select one or more of the items on
the stack and request TOP to display that data in one of the many tabular or graphical formats.

Data Modification and Analysis
TOP includes a feature called TOPCalcTM. TOPCalc allows you
to perform mathematical operations on the various supported data objects.
These operations include

Addition, subtraction, multiplication, division

Inversion, absolute value

Fast Fourier Transformer (FFT)

Inverse Discrete Fourier Transform (IDFT)

Square, square root

Power, energy, I2t, X-Y combine, integrate

Filter, time shift

Cumulative probability

Probability distribution

Waveform sampling

In addition to TOPCalc, TOP provides options to link units of measurement to a stack
item as well as enable per-unitization of the data.

TOP also provides the ability to produce new stack objects from user-specified expressions.
